The INTEC Group continues to grow

In 2014 the INTEC Group was expanded to include two new companies.

The newly established GTA INTEC GmbH, which is a merger of the Marco Polo Engineering GmbH and INTEC Engineering GmbH, is now part of the INTEC Group. GTA INTEC GmbH will continue supplying the range of products of STULZ GTA GmbH.

INTEC offers a complete range of heat engineering industrial equipment thanks to the vast experience and technical know-how of its CEO Edwin Karrer. These 20 years of experience in the fiel will now be supplemented by Sven Kneifel’s expertise, which will add the following applications to the already wide-ranging portfolio of the INTEC Group; regeneration-gas-heaters (FGH), sewage sludge, fluidized bed combustion and biomass incineration plants, as combined heat and power plants (CHP).

The second addition is due to the merger of INTEC Engineering GmbH and KonTroTec GmbH which specializes in contact drying technology. The INTEC Group will now offer its customers complete thermal sludge utilization technology. The innovative waste disposal and recycling concept is based on the combination of KonTroTec’s drying plants and INTEC Engineering’s solid combustion plants and process heat generation facilities.

The INTEC Agent Meeting in June 2013 ended with the inauguration ceremony of the new office building in Bruchsal.

Three days filled with good food, interesting lectures and lots of fun are over. INTEC Agents from more than 20 countries participated in the conference in Bruchsal.
Constantly developing the product range, improving current technologies and developing new technologies is a part of our philosophy.

Building of a hybrid solar-biomass plant in Spain

With a site of 70 hectares the plant will have an installed capacity of 25 Mwe and an estimated annual net production of 98,000 MW-hours. 

The main objective of the hybrid plant and eventually of the TES is to run the power plant 24 hours/day, when solar energy is not available.
This operation avoids daily turbine starts and shut-downs, increasing the life of the plant and ultimately the overall plant efficiency.

INTEC belongs alongside Siemens and MAN to the main technology suppliers that have been selected for the design and construction of the TSB power plant
